Perhaps I was unclear. I have a patch that removes the [token] syntax
from the GDB manual regarding async output.
I found your commit message that added a note that stated async
output does not necessarily include tokens.
The note made me think that at the time, you knew of at least one case
where async output would include the token (or you would have removed
the token syntax from the async output instead of saying that the token
might not be included).
Can you (or anyone) recall a case where GDB would output a token with an
async record?
I don't want to post a patch that removes the token syntax from the gdb
manual if indeed someone will run into it in the wild. That makes the
situation worse, not better.
